Step Fourth, test
OK, this step can start writing code, the process is not in detail, directly on the code
Copy Code code as follows:
Error_reporting (E_error | e_warning);
$im = new Imagick (' 1.psd ');
$im->setimageindex (0);
$im->setiteratorindex (0);
$im->stripimage (); Remove picture information
$im->setimagecompressionquality (80); Picture quality
$im->writeimage (' 1.jpg ');
The above code has been tested to correctly generate a 1.jpg
lazy or unable to buy a CD. You downloaded a rh62_install from an FTP. ISO such a document of more than 600 m. You're thinking this is a CD-ROM file, but you don't know how to undo it. What do we do?
ISO is the CD-ROM image file. What do you do if you want to pass the contents of a disc to someone completely? Of course, the simplest is the CD copy, if you want to go through the network, you can pass the files on the CD. If this disc is just a few files, but if the CD has such as CD-ROM can be
the system is 10 * 50 = 500, if a process occupies 4 m memory, then a total of 2G memory consumption, so you can see that in this configuration, the phase When memory is consumed, the advantage is that the system handles only 50 times of TCP handshake and shutdown operations.If KeepAlive is turned off, or if 50 users per second are accessed, if the user's number of consecutive requests is 3, then the total number of Apache process is 50 * 3 = 150, if the total memory consumption of 4 m memory,

manufacturers of authentic products prices, some small factory counterfeit goods prices are lower (how to debate the true and false will be discussed below), such a low price even if the average home users can afford.
Compared with CD-R or CD-RW, the price advantage of large-capacity hard disk + extraction box is self-evident, so we can calculate a sum of account. 1 13G hard drive + a 6.4g+2 box only 2500 yuan, and a cd-rw+ the price of a platter will be 2XXX, and only
A few days ago also encountered a large log file problem, the actual size of the database is 600M, the actual size of the log file is 33M, but the log files occupy a space of 2.8G!!!
Try a variety of ways, Shirnk DATABASE, TRUNCATE LOG file, there is no way to reduce the file. Anyway, this should be a bug in SQL Server.
Then find the following code, you can reduce the log file to the size you want. Copy the code into the Query Analyzer, and then mod
After you upgrade your LAN's network from 10MB/S to 100mb/s, you find that the network is not functioning properly.
In the LAN, when the network connection scope is bigger, the network transmission distance can be enlarged through the cascade between the hub. In the 10MB/S network can cascade four, the maximum transmission distance of the network reach 600m. However, when the network from 10MB/S upgrade to 100mb/s, if the use of common methods
Complete the operating system centos5.8 external 10G hard drive under the VM9 virtual machine.
1. First of all, the hard disk SDB is divided into 4 areas per district size 200M, respectively, sdb{5,6,7,8}. Four partitions will be built after PV
2. PV is then added to VG here to introduce the concept of PE .
Since VG is composed of multiple PE (blocks), the maximum number of PE per VG block is 65534. The default size of each PE is 4m
That is, the default of each VG is the maximum of 4m mu

SYBASE SYSTEM 11.0.0 for SCO UNIX 5.0.5
Installation Instructions
1. You must first determine that the NIC is properly configured on the system.
2. Log in as root, create Sybase user with scoadmin command, group belong to Sybase
Once the above two is confirmed, we can move to a phase of installation.

processor products drop down again, this 14TR current price looks very approachable, just 4399 yuan.
Dell's new 14R series in terms of shape compared to the previous generation of the change is quite obvious, the mold no longer use the front drift Yue screen design, a large number of metal-based body more quality and workmanship, which also meet the prevailing trend. The body thickness is also significantly reduced compared to the previous generation, and the reduction in weight and thickness
routers are 54M, but starting from 802.11n, the wireless router appears 150M, 300M, 450M or even 600M multiple speeds, and the router's nominal 750M and gigabit. After the advent of the AC router, the speed of the wireless router is even more chaotic, even the brand router hit 1900M speed.
In China, it's not surprising that manufacturers are bragging. Each family in the propaganda, generally put 5G and 2.4G speed, so ac433+n300 is said to be 750m,ac
Notebook graphics currently two major camps, respectively, Nvida graphics, AMD graphics card. In addition, Intel and AMD APU processors also have a built-in core graphics card, but the core graphics performance is relatively limited, can not be compared with the notebook independent graphics.
